恶意

This algorithm utilizes JND threshold model of DWT domain to embed watermark values, able to primely distinguish common image processing from vicious tamper and be sensitive to vicious tamper and effectively orient the region of tamper.

该算法能够很好的把一般图像信号处理与恶意篡改攻击区分开来，并且对恶意篡改是敏感的，能够很好的定位篡改区域。

Then they would launch remote attacks, and obtain the interactive access control rights, such as writing malice code in the parameter. Some service with such loopholes will send out an interactive shell to the destination address according to the malice code.

然后进行远程攻击，获得交互式访问权，比如通过远程缓冲区溢出，把恶意代码写在参数中，一些有着这样漏洞的服务就会根据恶意代码向目的地址发送一个交互式的shell。

The new protocol can detect and isolate the malicious nodes through using negotiatory mechanism during route discovery stage. At the same time, to save energy of nodes, blacklist and cache are introduced to resist the malicious nodes and avoid processing the duplicate data.

新协议在路由发现阶段采用节点协商机制，发现并隔离恶意节点，同时使用黑名单机制和cache机制，剔除恶意节点的影响并避免对相同数据重复处理，达到节省能量的目的。
